The catheter mount with double swivel connector and flexible tubing provides mobility and flexibility to the patient end of the circuit. A typical corrugated circuit creates resistance as the flow of gas moves through it. The corrugated surface creates turbulence (see diagram below) and this creates resistance. Furthermore, the more flow you give your patient, the more resistance created and the more you will compromise your ventilator and therapy. CORR-A-FLEX Tubing is flexible, lightweight, and disposable. Its collared tubing end slips on and locks to 22mm adapters for secure fit.
